CENTRIFUGAL MACHINE.

SPECIFICATION forming part of Letters Patent No. 343.932, dated June 15,18816.

Application filed May 5. 1886. Serial No. 201,253.

To alZ whom it may concern.-

Be it known that I, ADOLF VVALDBAUR, doctor of philosophy, 2. subject ofthe King of WViirtembergend residing at Augsburg,Kingdom of Bavaria,German Empire, have invented new and useful Improvements in GentrifugalMachines, whereof the following is a specification.

With the present arrangements for carrying out the different processesof bleaching,dyeing, washing,drying,&c., of textile fibers,yarn,andthelike, the ware has to be repeatedly removed from one apparatus to theother. This causes much waste of time. a The ware, which is apt to comeoutof order by the operations, requires to be frequently repacked, andis exposed to the danger of being damaged, and the requisite apparatusesare complicated and expensive.

The object of my invention is to provide means for carrying out thevarious aforesaid processes one after the other without removing orrepacking the ware, for preventing the layers of the same from shifting,and for causing it to be compressed in proportion to the strength of thecurrent of fluid passing through the material. For this purpose I employa centrifugal machine, the rotating basket whereof is provided with acover fitting loosely into it, in combination with guiding devices,whereby the cover, when supported by elastic or compressible materialpacked into the basket, will be caused to screw itself down within thebasket in consequence of its tendency, resulting from inertia, to remainbehind relatively to the basket while rotating. Moreover, I arrange inthe middle of the latter a small longitudinally-resilient and thereforecompressible basket having orifices, and serving to produce and maintaina hollow space,from which the fluid designed for the treatment of the material percolates the latter. This basket may be provided withcontrivances for conducting the fluid toward its periphery.'

The invention also comprises means for drawing off noxious gases andvapors emanating from the liquids employed,and also adapted for suckingair or gases through the matevrial under treatment.

On the annexed sheet of drawings a centrifugal machine constructedaccording to my invention is represented in two different arrangements.

(No model.)

Figure 1 shows the complete machine of the first arrangement insectional elevation. Fig.

2 is a plan of the basket; Fig. 3, a top view of the cover of thelatter. Figs. 4 and 5 show,in sectional elevation and in plan and to alarger scale, the inside basket. Fig. 6 isa sectional elevation, andFig. 7 a plan, of the main basket with cover of the second arrangement.

On the inner surface of the wall of the basket T, Figs. 1 and 2,arefixed three or more inclined ledges,a, which thus form parts ofscrewthreads, and the cover D, Figs. 1 and 3, is provided withcorresponding notches, b, the sides whereof constitute the counterpartsoi'the said threads. The incline of the ledges a is such that thecover,inserted into the basket while at rest and turned in a directioncontrary to the normal rotation of the basket, willscrew itself down onthe ledges a. The said ledges terminate at their upper ends in screwsprovided with thumbnuts. The inner basket,K,is made of strips of metalplaited together, and it is provided on the inside with gutters c, fixedto the said strips and extending toward the centre of the basket. Bythese gutters the liquid flowing in from above is conducted to theperiphery of the said basket The supply-pipe Zfor the liquid fits withits conical end into the tubular projection E of the cover D, and it isprovided ate with a joint for allowing it to be turned back and to sinkwith the cover.

The means for removing noxious gases and Vapors and drawing air andgases through the machine consists in a pipe, V, communicating with thecasing M and leading to an exhauster, and in a cover, G, for closing thecasing. Supposing the basket T to be filled with the material to betreated, the cover D is placed upon the latter, so that the screws fproj ect through the notches b. It is then pressed down by thethumb-nuts until the notches register with the guiding-ledges a.Thereupon the basket is put in rotation. During this rotation the coverD tends to remain behindin respect to the basket, in consequence of itsinertia, and from this follows that it will screw itself down on theledges a, so as to compress the material. This effect is greater inproportion as the basket runs quicker. As soon as a sufficient speed isattained,

the supply-pipe Z is turned down and introduced with its conical endinto the tubular proj ection E of the cover D. Communication with ICO 'the reservoir containing the liquid to be used having then beenestablished, the latter is drawn into the basket Kby the sucking actionof the centrifugal force, and distributed upon the periphery of thebasket by the gutters 0. The said sucking action also tends to keep thepipe Z tight in the tube E. \Vith the increase of speed of thebasket,and the consequent increase of compression of the material,theforce with which the 1iquid is drawn through the latter becomes greater.The current of the liquid thus regulates itself automatically, accordingto the degree of compression of the material, while at the same time thelayers thereof are prevented frorn'shifting by the action of thecentrifugal force, and from thus coming out of order. In the measure, asthe coverD descends, the basket K is compressed, together with thematerial, in vertical direction,so that a free space for the passage ofthe liquid will constantly be maintained in the center of the basket T.In case gases or vapors are to be drawn off, or to be sucked through thepipe Z and the material, the casing M is closed by the cover G, and theeXhauster connected to the pipe V is put in operation. v

By means of the described machine the dif ferent processes ofbleaching,dyeing,and washing, and also of drying by air and treating bygases may be carried out in succession without removing the ware fromthe machine.

The modified arrangement of the basket T and the coverD (shown by Figs.6 and 7) consists in an inversion ofthe means for guidingthe latter,

the cover being in this case provided with ribs a, whose upper edgesform screwsurfaces, while to the basket are fixed pins or rollers I),under which slide the said ribs. The operation of this arrangement isthe same as that of the one described first.

I claim as my invention- 1. In a centrifugal machine, the combination,with the basket T and the cover D, of

screw surfaces and corresponding counterparts adapted to cause thecover,supported by elastic material, to screw itself down within thebasket, when, in consequence of its inertia,the said cover rotates at alower speed than the basket, substantially as and for the purposedescribed.

2. The c0mbination,with the basket T, having guiding-ledges a, formingportions of screwthreads, of a cover, D, provided with notches b,fitting upon the said ledges,substantially as and for the purposespecified.

3. The combination, with the basket T and cover D, of the basket K,constructed to be resilient lengthwise, and having orifices for thepassage of fluid, substantially as and for the purpose set forth.

4. The combination, with the basket T and the cover D, of thelongitudinally-resilient basket K, having orifices, and to the inside ofwhich are fixed gutters c, as and for the purpose described.

5. The combination, with the basket T, cover D,and casing M, of thecover G, pipe Z, for the supply offluid,and pipe V,leading from thecasing M to an ex'hauster, substantially as described, and for thepurpose set forth.

In testimony whereofI'have hereunto set my hand in the presence of twosubscribing witnesses. p

ADOLF WALDBAUR.
